Answer: $0.3 ; $1.05
Step-by-step explanation:
Price of candy = $0.75
Mark up = 40% = 40/100 = 0.4
(a) Amount of the markup = Price × Mark up percent = $0.75 × 0.4 = $0.3
(b) Amount charged by the concession stand for each candy bar will be:
Price of candy + Mark up amount
= $0.75 + $0.30
= $1.05
A9*8a4
Final result :
23a13
Step by step solution :
Step 1 :
Equation at the end of step 1 :
23a9 • a4
Step 2 :
Multiplying exponential expressions :
2.1 a9 multiplied by a4 = a(9 + 4) = a13
Final result :
23a13
Answer:
... you <u>add</u> the exponents
Step-by-step explanation:
An exponent is a way of showing repeated multiplication. For example, ...
x^2 means x·x
and
x^3 means x·x·x
If we multiply these two expressions together, we get ...
(x^2)·(x^3) = (x·x)·(x·x·x) = x·x·x·x·x
This is a product in which x appears as a factor 5 times, so we can write it using an exponent as ...
x·x·x·x·x = x^5
___
That is, when we multiply the expressions, we add the numbers of times the factor appears in the product:
2 + 3 = 5
x^2 · x^3 = x^(2+3) = x^5
